"?hirsutum" (Ehrenberg, 1837b, pl.1, figs.10,?13) Lentin and Williams, 1973, p.102.  Name not validly published: Ehrenberg (1837b) did not intend to introduce a new species.  Originally Xanthidium hirsutum (name not validly published; Appendix A), subsequently Ovum hispidum subsp. hirsutum (name not validly published; Appendix A), thirdly Hystrichosphaera hirsuta (name not validly published), fourthly Hystrichosphaeridium hirsutum (name not validly published), fifthly Baltisphaeridium hirsutum (name not validly published; Appendix A), sixthly Operculodinium hirsutum (name not validly published), seventhly Operculodinium? hirsutum (name not validly published).  Questionable assignment: Stover and Evitt (1978, p.179).  According to Fensome et al. (1990, p.102): "It is apparent from the discussion given by Sarjeant (1984a, p.131–132) that Ehrenberg (1838 [1837b herein]) did not intend to introduce a new taxon but was comparing fossil specimens with Xanthidium (now Staurastrum) hirsutum Ehrenberg, 1838 [1837b herein], a species of extant desmids.  Thus the microfossil species name Xanthidium hirsutum and derivatives (Hystrichosphaeridium hirsutum, Hystrichosphaera hirsuta and Operculodinium hirsutum) are not validly published according to I.C.N. Article 36.1a.  The specimen illustrated and provisionally identified as Xanthidium hirsutum by Ehrenberg (1838 [1837b herein]) is a specimen of Coronifera striolata ... according to Sarjeant (1984a, p.131–132)." Yun Hyesu (1981, p.29) considered Xanthidium hirsutum of Ehrenberg (1837b) to be a possible taxonomic junior synonym of Hystrichosphaeridium (now Pervosphaeridium) pseudhystrichodinium.  Age: Late Cretaceous.
